I am looking for a Donald Stewart. Born in 1878 of Scotland/ or Tombstone, AZ. He passed away on June of1925 in Oruro, Bolivia. In the past he had been a minor and we believe that he was still one while in Bolivia. He had a relative by the name of David Stewart or sometimes known as George Wilson. He also had a close friend by the name of Gaspar Nicolls.
Or if anyone has any information on miners in Bolivia between 1915-1925 I would love to hear from you.
